i am using Monthly Mean data of Hadisst1 data for the period of 1901-2012 i.e. for 112 years and i extracted the JJAS mean time series from this data set after that i searched the mail archives and the documentation for spatial plot of trend and co-relation but i didn't get any such information about these plots. i want to spatial plot of trend for JJAS mean SST and co-relation of SST ( pacific versus global ocean) for JJAS mean. one more thing i need to know that how to get spatial plot of trend suppose for SST as (degree Celsius/year or degree Celsius/Decade)
this is the specification for my data
currently SET data sets:
name title I J K L M N
SST sea surface temperature (degc) 1:340 1:60 ... 1:1344 ... ...
sh gr sst
name axis # pts start end
LON191_530 LONGITUDE 340mr 10.5E 10.5W
LAT61_120 LATITUDE 60 r 29.5S 29.5N
TIME TIME 1344 i 01-JAN-1901 00:00 01-DEC-2012 00:00
i hope i will get some solution for these type of plotting.
